The University of Berlin, partnered with the Budapest University of Technology and Economics, as well as Universita Politecnica delle Marche in Italy, have found a way to squish 500GB of data into one HD DVD.

Under normal methods of storage, a Blu-Ray disk holds 25GB of data. An HD-DVD holds 15GB, and a dual layer HD-DVD holds 30GB. However, the universities have managed to modify where the recording laser puts the data. By "using nanostructures inside the disk rather than on the surface as in conventional optical storage systems", the Microholas project has found a way to put 500GB onto one HD DVD. The universities look forward to pushing this project to it's full potential, which could mean a Terabyte of data on a single HD-DVD disk.
